The washers I took off my heads (Type 4) 30 years ago got mixed in with my other hardware. I fished out 16 M10 washers that fit, but want to make sure I'm installing correct washers and maybe source some new ones if needed. PET just lists:
washer A 10,5 Are they special thickness or hardness etc.? BTW, anyone know what the "A", "B", etc. for hardware specs in the PET mean? I haven't been able to find a key. Must be looking in the wrong place. |

Yes, they are harder than regular washers.
You need to use the correct ones or they will smash and bad things can happen. |

Exactly what I would have guessed. Would these from Belmetric work? https://www.belmetric.com/hardened-metric-f...in-p-10688.html |

I'll take you up on it. I just measured one of the washers I have which I'm pretty sure was an actual head washer. It is both thicker and larger O.D. than the Belmetric ones. Given the critical nature of this part, I'd rather not make guesses. I'll PM you. |
